Beams have inconsistent behavior from Studio to Engine

Reproduction Steps
I currently cannot reproduce this outside of my own project. If anybody has information on reproduction steps, feel free to leave the steps in the replies below!

A project file of the game may only be given to Roblox Staff to protect contracts binded to the parent studio.

Expected Behavior
Beams should not have issues displaying when transferring between Studio and Engine. In my example video, both Studio and Engine should have tracers, not just Studio.

Actual Behavior
Here is a video of the issue reproduced:

In this given example, bullet tracers are created with Beams; both the beams and attachments are parented under Terrain on the client side. In-engine, the beams do not show.
